很多时候，处于某些特殊的原因，我们会使用一些特殊的字段，所以，joomla自带的注册字段不符合要求，这个时候，rsform可以提供我们一个比较好的解决方案

首先在rsform中，创建一个可以使用的类似注册的form，字段包含：name，username，email，password以及一个submit，自动生成的form layout应该类似于

<div class="componentheading">{global:formtitle}</div>
{error}
<table border="0">
	<tr class="rsform-block rsform-block-username">
		<td>{username:caption}</td>
		<td>{username:body}<div class="formClr"></div>{username:validation}</td>
		<td>{username:description}</td>
	</tr>
	<tr class="rsform-block rsform-block-name">
		<td>{name:caption}</td>
		<td>{name:body}<div class="formClr"></div>{name:validation}</td>
		<td>{name:description}</td>
	</tr>
	<tr class="rsform-block rsform-block-email">
		<td>{email:caption}</td>
		<td>{email:body}<div class="formClr"></div>{email:validation}</td>
		<td>{email:description}</td>
	</tr>
	<tr class="rsform-block rsform-block-password">
		<td>{password:caption}</td>
		<td>{password:body}<div class="formClr"></div>{password:validation}</td>
		<td>{password:description}</td>
	</tr>
	<tr class="rsform-block rsform-block-submit">
		<td>{Submit:caption}</td>
		<td>{Submit:body}<div class="formClr"></div>{Submit:validation}</td>
		<td>{Submit:description}</td>
	</tr>
</table>

注册的form我们写完了，接下来，我们要把填写的数据传给joomla的数据库，在Script那个tab类面第三个Script called after form has been processed的textarea填写如下code 

<?php
// load language
$lang = JFactory::getLanguage();
$lang->load('com_user', JPATH_SITE);

// get config for com_users
$usersConfig = &JComponentHelper::getParams( 'com_users' );

// get the ACL
$acl =& JFactory::getACL();
 
// "generate" a new JUser Object
// it's important to set the "0" otherwise your admin user information will be loaded
$user = JFactory::getUser(0);
 
$data = array(); // array for all user settings
 
// get the default usertype
$usertype = 'Registered';
 
// set up the "main" user information
 
$data['name'] = $_POST['form']['name']; // add first- and lastname
$data['username'] = $_POST['form']['username']; // add username
$data['email'] = $_POST['form']['email']; // add email
$data['gid'] = $acl->get_group_id( '', $usertype, 'ARO' );  // generate the gid from the usertype
 
/* no need to add the usertype, it will be generated automaticaly from the gid */
 
$data['password'] = $_POST['form']['password']; // set the password
$data['password2'] = $_POST['form']['password']; // confirm the password
$data['sendEmail'] = 1; // should the user receive system mails?
 
$data['block'] = 0; // don't block the user

// If user activation is turned on, we need to set the activation information
$useractivation = $usersConfig->get( 'useractivation' );
if ($useractivation == '1')
{
	jimport('joomla.user.helper');
	$user->set('activation', JUtility::getHash( JUserHelper::genRandomPassword()) );
	$data['block'] = 1;
}

if (!$user->bind($data)) { // now bind the data to the JUser Object, if it not works....
    JError::raiseWarning('', JText::_( $user->getError())); // ...raise an Warning
    return false; // if you're in a method/function return false
}
 
if (!$user->save()) { // if the user is NOT saved...
    JError::raiseWarning('', JText::_( $user->getError())); // ...raise an Warning
    return false; // if you're in a method/function return false
}

// Send emails
require_once(JPATH_SITE.DS.'components'.DS.'com_user'.DS.'controller.php');
UserController::_sendMail($user, $data['password']);
?>

这样的话，这个form就可以用来注册用户了。

另外，有些特殊的要求，比如说，注册之后，要自动登录，那加入以下的code 

<?php
//auto login
$usersipass['username'] = $_POST['form']['name'];
$usersipass['password'] = $_POST['form']['password']; 
$mainframe->login($usersipass);
$mainframe->redirect( 'index.php' );
?>
